Tumblecloud is a new platform for piecing together music, videos, photos, and also websites into dynamic slideshows that you can share with others. Currently in beta, the free webapp can be used for "collaborative digital storytelling," as the founders describe it, for business or personal purposes.

The built-in video editor lets you quickly create a video using actual videos or images, add music, insert notes and website screengrabs, and more. There's a library of media you can add to get started (or you can upload your own), and others can also contribute to your shared projects, making tumblecloud possibly a great tool for sharing creative work with clients or with a group of creative friends.

Try out the workbench as a guest without logging in or sign up for an account to save and share your streams.
